J Cardiovasc Magn Reson
. 2024 Mar;
26(1):101041.
PMID: 38527706
Cardiovascular magnetic resonance (CMR) has become the reference standard for quantitative and qualitative assessment of ventricular function, blood flow, and myocardial tissue characterization. There is a preponderance of large CMR...

J Cardiovasc Magn Reson
. 2024 Feb;
26(1):101029.
PMID: 38403073
Background: Identification of risk factors for biventricular (BiV) repair in children with hypoplastic left ventricles (HLV) has been challenging. We sought to identify preoperative cardiovascular magnetic resonance (CMR) predictors of...

. 2024 Jan;
4(1):oead138.
PMID: 38223303
Aims: Coarctation of the aorta is associated with long-term morbidity including decreased exercise capacity, despite successful repair. In the absence of discrete recoarctation, the haemodynamic mechanism remains unknown. This multicentre...

. 2024 Jan;
83(1):63-81.
PMID: 38171712
Recent years have witnessed exponential growth in cardiac imaging technologies, allowing better visualization of complex cardiac anatomy and improved assessment of physiology. These advances have become increasingly important as more...

PMID: 37904806
Introduction: As the life expectancy of children with congenital heart disease (CHD) is rapidly increasing and the adult population with CHD is growing, there is an unmet need to improve...

J Cardiovasc Magn Reson
. 2023 Sep;
25(1):51.
PMID: 37759303
Background: Some patients with pulmonary atresia with an intact ventricular septum (PA/IVS) or a left ventricle dominant atrioventricular canal defect (LDAVC) with a hypoplastic right ventricle (RV) and univentricular (1 ...

Front Cardiovasc Med
. 2023 Aug;
10:1141027.
PMID: 37600046
Background: The right ventricle (RV) has complex geometry and function, with motion along three separate axes-longitudinal, radial, and anteroposterior. Quantitative assessment of RV function by two-dimension echocardiography (2DE) has been...

J Cardiovasc Magn Reson
. 2023 Jun;
25(1):28.
PMID: 37303061
Background: Lymphatic complications are common in patients with Fontan circulation. Three-dimensional balanced steady-state free precession (3D bSSFP) angiography by cardiovascular magnetic resonance (CMR) is widely used for cardiovascular anatomical assessment....

. 2023 May;
10:1137814.
PMID: 37215544
Background: Accurate measurement of ventricular volumes is an important clinical imaging goal. Three-dimensional echocardiography (3DEcho) is used increasingly as it is more available and less costly than cardiac magnetic resonance...
